Hope thats clear as mud lol (its the admin tree view if you like)
anyway when a visitor gets down to BikePage level the get the details and pics for the bike make and model i.e one entry
now on that page ive created a css scroller to scroll image1 of my many-many images (using an if exists loop) this works mint. but i can only filter it by inputting the NewbikeHolder Id in manually, so when a visitor is viewing Make3 Bike 3 he sees scrolling images for Make1 bikes.

anyway here is the code i need to filter and perhaps it will make perfect sense.
